1. [OT] another floppy question

I dug out a box of about 200 floppy disks today - old stuff I wrote 5-10 years ago, and tried to look thru them. Some - maybe 1 out of 3 - could be read, the others, which I'm sure *used* to have data on them, were unreadable. OK, so maybe data fades away over the years, no great loss. I'll just re-format these disks and use them for something else, right ? Wrong. Barely 1 out of 10 could be formatted using DOS 6.2, Windows 98, or Linux. The rest return errors, usually in track 0. So I'm stuck with a huge pile of unusable disks. Before you say something is wrong with my disk drive, let me point out that I have 3 pc's and 5 floppy drives. Results are the same regardless. I expect stuff in the fridge to go bad after a while, but disks? Irv

These days I burned CD-R with my old stuff from floppies. 470 - (1.44/3'')- 3 bad, 43 have 1..2 files with bad sectors. 138 - (1.2/5'') - all good. 80 - (720k/5'')- 3 have 1 file with bad sector. Maybe, just the hot climate of your land? Regards, Igor Kachan kinz at peterlink.ru

Perhaps. If I had any software worth saving, I would try to write it to CDs. Does anyone yet have a good idea of how long CDs will remain readable?

Also moisture is not good, I suppose. And someone told me, that (cigarrete) smoke also is harmful to floppies. I don't know, if this is true, but I can imagine that very well. > If I had any software worth saving, I would try to write it to CDs. > Does anyone yet have a good idea of how long CDs will remain > readable? High-quality CDs and DVDs: 100-200 years (estimated). [Source (in German): http://www.monitor.co.at/story.cfm/storyid/4704] > (Am I wrong in thinking that paper tape may be the best archival > method? :) AFAIK yes, but it depends. Cheap paper contains acid, which is especially harmful to the paper. The best paper for very long time data storage is what we call "Buettenpapier" in German. That is paper, that consists of cotton.

I'm glad i am not the only one with this problem. I use zip disks now if i need removeable media, i've never had a zip fail. Kat

Mold and things. Deteriorating materials, for sure. CBS once shipped crates of Phillips audio cassettes, without running them thru QC. Why no quality control? Because in the hour it took to get them from the recorders to the loaders, the glue holding the ferrite to the mylar rotted. One pass thru the pinch rollers in a player would break all the ferrite off and you'd have clear mylar left. I am not joking. If QC played the tapes to check them, they'd be garbage. For recent high profile cases of people not caring, see: Bush being elected president, the NASA disasters (including the Gemini and Apollo fires), the Bophal disaster, the drunk driving the Exxon Valdez, the guy shooting holes in the Alyeska oil pipeline for fun, the unpleasantness in Sri Lanka, etc. > Perhaps. > If I had any software worth saving, I would try to write it to CDs. > Does anyone yet have a good idea of how long CDs will remain > readable? There is a mold that eats the aluminum in CDs. It gets in along the rim, and progressively eats it's way into the disk. Obviously, with no aluminum left, there is no data left. At least the explaination i saw was that the mold eats the aluminum, which i have a problem with.. i say the mold eats the adhesives, and the mold byproducts, the oxygen or acids, eats the aluminum. Rather like the copper mold on card-edge connectors. There's no cure mentioned. There is a rule to the effect that as soon as the mass of people switch to a specific data storage media, it will stop being made. How many companies make mfm controller cards anymore? How many of you still buy one mil cobalt tape on 10inch reels? Some things always change, alas not always for the better. I still keep candles and a fire source nearby for when (not if) the power goes out. > (Am I wrong in thinking that paper tape may be the best archival > method? :) Well, maybe, if you don't have termites? I calculated once that to archive win95 on paper tape would take over a year to read back in. Gimme a year to reboot the computer? I knew a company that still used paper tape in the mid 80's. Whatever you do, get rid of the olde acetate tapes you have! Kat

Maybe it is a combination of factors: Combine heaper disks, higher storage density, and dirt cheap drives, and you get stuff that just barely works. Irv - who can remember when 360k 8" drives cost $500.

I can't read German, but that has to be stamped, factory made gear, not the home-written stuff, or marketing blurb, not reality.. I've read some bad reviews on CDRs: just a few months, under heavy use (especially if you leave a disk in the drive for any length of time), and really only several years even when stored in optimal conditions. I think Ricardo Forno recently had some bad experiences. Pete

However search the web for "click of death". No panic, just something every zip drive owner should be aware of. I'm very happy (so far, touch wood) with my zip drive. Pete

Here is a more comprehensive soure, in English: http://www.faqs.org/faqs/cdrom/cd-recordable/part4/ See "Subject: [7-5] How long do CD-Rs and CD-RWs last?" Of course, the lifetime of CD-Rs at least depends on the quality of the CD-R disc, and on how the disc is handled and stored. > I've read some bad reviews on CDRs: just a few months, under heavy use > (especially if you leave a disk in the drive for any length of time), > and really only several years even when stored in optimal conditions. > > I think Ricardo Forno recently had some bad experiences.

I think I can summarise it as: 1) Fairly obviously, always use full round labels, handle disks with extreme care, and store somewhere cool, dark, and dust-free. 2) Experiment with different brands until you find the best for your hardware, climate, and shoe size. What works for one person will not necessarily work for someone else. 3) Quality/cost/reputation are unreliable factors. There is no real option other than doing your own tests. Pete

There is no real > option other than doing your own tests. After buying my CD burner, I did some tests with different CD-R blanks. I found a brand, that worked good with my CD burner, but some weeks later, the factory cancelled the production of this brand! This is, what we call "modern times", isn't it? There is also another pitfall: Many of the "big name" media manufacturers don't actually make their own media. Instead, they buy from other manufacturers and stamp their logo on the discs. Generally speaking, this isn't a bad thing, but those companies often buy from *different* manufacturers!! CD-R blanks labelled "BASF", are for instance produced by Ritek, CMC Magnetics, Taiyo Yuden, Kodak, or Pioneer (this list might not be complete). So maybe, someone thinks s/he is testing "BASF" CD-R blanks, but actually is testing blanks, produced by say Taiyo Yuden. Then s/he thinks: "This is a good brand for my CD burner", goes back to the same store one week later, and buys 100 "BASF" CD-R blanks. But this time, s/he actually bought CD-R blanks produced by say Ritek. This is just juggling with names. That's one reason, why I for instance can recommend "Verbatim Data Life Plus" CD-R blanks. They are *always* produced by Mitsubishi Chemicals, and they were rated good in several tests, that I read. Anyway, one should first buy only a few blanks, and test them with one's CD burner. But in any case beware of the pitfall of name juggling! Best regards, Juergen PS: I don't hold shares of Mitsubishi Chemicals. -- /"\ ASCII ribbon campain | |\ _,,,---,,_ \ / against HTML in | /,`.-'`' -. ;-;;,_ X e-mail and news, | |,4- ) )-,_..;\ ( `'-' / \ and unneeded MIME | '---''(_/--' `-'\_)
